Claims. 7 (01. 40-70) This is a division of my application Serial No. 750,805 filed October 31, 1934, for Letters Patent of the United States for improvement in comput- 4 ing and registering mechanism for liquid dispens- 5 ing apparatus. Said registering mechanism includes pairs of rotary dials, supported in coaxial relation one behind the other for cooperative display of numbers on the dials of each pair through windows in a stationary panel; one pair of dials respectively representing gallons and fractions of a gallon dispensed and the other pairiof dialsqepresenting dollars and fractions of a dollar}: value of the liquid dispensed. In order to facilitate the relative rotary adjustment of said dials with respect to their supports, in

the initial calibration oi the registering mechanism, orthereaiter, without removal of said panel, I provide each dial with screw means for detachably-connecting it with its rotary support and provide holes in said panel and in the outer dials J with which the screw means may be registered for manipulation by a screw driver inserted through the holes. Moreover, I find it convenient to provide said panel with a movable slide cover by which said holes through the panel may be .op'ened or closed; said cover being accessible only from the back of the panel; whereby unauthorized adjustment of said screw means may be pre vented.

My invention includes the various novel features of construction and arrangement herein after more definitely specified.

In said drawings; Fig. I is an elevation of said panel and the dial structure provided with indi- 35- eating means adapted for registration'with the windows and screw holes in said panel.

Fig. 11 is an elevation of said dial structure with the panel removed.

Fig. III is a fragmentary vertical sectional view,

taken on the line III, III in Figs. I and H, showing an axial sectional view of the dials and their supporting means.

Referring to Fig. I, the stationary panel I has the window 2 for the display of rotary dials l and 4 respectively graduated with circumferential series of marks indicating fractions of a gallon and gallons, which marks are caused to successively register with the stationary index pointers 5 and 6. Said panel has the window 8 for the display of rotary dials 9 and I0 graduated with circumferential series of marks indicating fractions of a dollar and dollars, which marks are.

caused to successively register with the stationary index pointers II and I2. v

ReferringtomaIIandIILsaiddia-Hisdetachably rigidly connected with the huh I 3, which is pinned on its axial shaft I4, by a circumferential; series of three screws I5 extending through arcuate slots I 8 in said dial 3, and said screws l5 are accessible from the exterior of said panel 5 l by selectively registering them with the hole It in said panel so that a screw driver may be inserted through said hole Win engagement with any. one of said screws I5 to remove or replace them. Said dial 4 is similarly rigidly connected if) with the hub 20, which is journaled on said hub It, by a circumferential series of three screws 2I extending through arcuate slots 22 in said dial 4. Said screws 2I may be registered with holes 24 in said dial 2 and with the hole 25 in said stationary panel I so that a screw driver may be inserted through said holes 24 and 25 in engagement with any one of said screws 2! to remove or replace them.

Said dial III is similarto said dial 3 in that 20 it is rigidly connected with its hub 21, pinned on its axial shaft 28, by a circumferential series of three screws 29 extending through arcuate slots III in said dial in. Said screws 2! are accessible from the exterior of said panel I by selectively 25 registering them with the hole 2| in said panel so that a screw driver may be inserted through said hole 3| in engagement with any one of said screws 29 to remove or replace them. Said dial 0 is similar to said dial 4 in that it is rigidly 80 connected with the hub 32, which is journaled on said hub 2'I,'by a circumferential series of three screws 34 entered through arcuate slots 35 in said dial 9. Said screws 24 may be brought into registry with holes 36 in said'dial III and with the 8 hole 31 in said stationary panel I so that a screwdriver may be inserted through said holes 31 and 38 in engagement with any one of said screws 34 to remove or replace them.

Said stationary panel I supports the slide cover 40 38 by means of studs 29 rigidly connected with said panel and extndingthrough slots 42 in said cover, and, as indicated in Fig. I, said cover is so shaped that it maybe used to simultaneously open and close all of said'holes ll, 25, II, and 41 in said panel to afford or prevent access to the dial screws aforesaid.

As indicated in Fig. III, said shafts I4 and 28 are journaled in the opposite end walls 42 and 43 connected by the bottom wall 44 and top wall 45 to form a casing for mechanism for actuating said dials, and I find it convenient to duplicate said stationary panel and rotary dials at opposite ends of said casing so as to simultaneously manifest the similar dial numbers upon said op- I posite ends. Said panels are respectively supported in rigid relation with said end walls 42 and 43 by brackets 4i and I1.

However, I do not desire to limit myseli to the precise details of construction and arrangement herein set forth, as it is obvious that various modifications may be made therein without departing from the essential features my invention, as defined in the appended claims.

I claim:

1. In a computing registering mechanism ior liquid dispensing apparatus, a stationary panel having a window opening for displaying indicating means; indicating means for eii'ecting such display including a rotary dial; an axial shaft for said dial; screw means for detachably connecting said dial with said shaft; a hole in said panel with which said screw means may be registered for removal by a screw driver inserted through said hole; and a slide cover for said hole carried by said panel; whereby, when said slide cover is moved to open said hole, said dial may be removed and replaced without removal oi said panel.

2. In a computing registering mechanism, a stationary panel having a window opening for displaying indicating means; indicating means for eiIecting such display including a rotary dial; an axial shaft for said dial; screw means for detachably connecting said dial with said shaft; and a hole in said panel with which said screw means may be registered for removal by a screw driver inserted through said hole; whereby said dial may be removed and replaced without removal of said panel.
